Before the arrival of the Minnesota Twins from Washington, D.C., in 1961, there was a long history of minor league baseball teams called the St. Paul Saints, as well as their crosstown rivals the Minneapolis Millers.

Johnson, a Cincinnati-based reporter, had been recommended by his friend Charles Comiskey, former major league star with the St. Louis Browns in the 1880s, who was then managing the Cincinnati Reds.

When the Minnesota Twins came to town in 1961, the Saints became the Omaha Dodgers while the Millers ceased operations and their role as affiliate to the Boston Red Sox was filled by the Seattle Rainiers.

During the six decades of the original American Association minor league, the Minneapolis Millers and St. Paul Saints engaged in vigorous rivalry known as the Streetcar Series.

This series has been documented in a book by Rex Hamann entitled The Millers and the Saints, Baseball Championships of the Twin Cities Rivals (2014).

In spite of an initially cool, if not outright hostile reception, the Saints and their major league neighbor (less than 10 miles (16 km) away) have worked together for several years to promote the sport of baseball.

Mike Veeck wrote a book that covered the mantra "Fun is Good" (2005) and describes the business approach he has used for many years.

The proposed 7,500-seat stadium would be located in the Lowertown neighborhood near a planned maintenance facility for the METRO Green Line light rail.

The Saints began competition as a Twins affiliate on May 4, 2021, with an 8–2 loss to the Omaha Storm Chasers at Werner Park in Papillion, Nebraska.
